Configure The Dialer Interface - Cisco 1812W - Integrated Services Router Wireless Configuration Manual

Chapter 3 Configuring PPP over Ethernet with NAT

Configure the Dialer Interface

The dialer interface indicates how to handle traffic from the clients, including, for example, default
routing information, the encapsulation protocol, and the dialer pool to use. The dialer interface is also
used for cloning virtual access. Multiple PPPoE client sessions can be configured on a Fast Ethernet
interface, but each session must use a separate dialer interface and a separate dialer pool.
Complete the following steps to configure a dialer interface for one of the Fast Ethernet LAN interfaces
on the router, starting in global configuration mode.
Command
Step 1 interface dialer dialer-rotary-group-number
Example:
Router(config)# interface dialer 0
Router(config-if)#
Step 2 ip address negotiated
Example:
Router(config-if)# ip address negotiated
Router(config-if)#
Step 3 ip mtu bytes
Example:
Router(config-if)# ip mtu 1492
Router(config-if)#
Step 4
encapsulation encapsulation-type
Example:
Router(config-if)# encapsulation ppp
Router(config-if)#
Step 5
ppp authentication {protocol1 [protocol2...]}
Example:
Router(config-if)# ppp authentication chap
Router(config-if)#
Step 6 dialer pool number
Example:
Router(config-if)# dialer pool 1
Router(config-if)#

Cisco 1800 Series Integrated Services Routers (Fixed) Software Configuration Guide
Configure the Dialer Interface
Purpose
Creates a dialer interface (numbered 0–255), and
enters interface configuration mode.
Specifies that the IP address for the interface is
obtained through PPP/IPCP (IP Control Protocol)
address negotiation.
Sets the size of the IP maximum transmission unit
(MTU). The default minimum is 128 bytes. The
maximum for Ethernet is 1492 bytes.
Sets the encapsulation type to PPP for the data
packets being transmitted and received.
Sets the PPP authentication method to Challenge
Handshake Authentication Protocol (CHAP).
For details about this command and additional
parameters that can be set, see the
Security Command Reference.
Specifies the dialer pool to use to connect to a
specific destination subnetwork.
